If buying for Subs, you will struggle

Quality that I am confident in when it is all on the line.

CMMG 16" 300 BLK Barrel
Awesome barrel that gives me the accuracy I need for my custom build. It can be difficult to find the sweet spot of accuracy vs cost when shopping for AR barrels but this one seems to have found it for me.
